GAUGING AND MARKING INSTRUMENT FOR i DBAVVEE, BULLS AND BOOK HANDLES y Francis L ut z, Merced, Calif. Application June 13, 1939, Serial No. 278,809 8 Claims. (o 33-189) s This invention relates generally to carpentry and more particularlyv to gauges and markers therefor.

An objector the invention is to provide an in strument facilitating the installation of builders hardware and particularly adapted for use in gauging and marking drawers and cupboard and cabinet doors for pulls and handles, all in such manner as to expedite andsimplify accurate installation of such hardware.

Another object of the invention is to provide an I "instrument of the above described character which is readily adjustable to accommodate drawers and doors of various sizesycan be securely uniform installation of the hardware on any number of drawers and doorsdesiredy and can bearranged into a fiat, compact parcel when not in use so as to require only a small space in a tool box. a

With these and other objects in view. the invention resides in the combinations and arrangements of elements as set forth in the following specification and particularly pointed out in the appendedv 25 claims. 7

In the accompanying drawing,

Figure l. is a view showing in front elevation.

the front of a drawer for the gauging and marking thereof for a single handle: 1

Figure '7 is a view similar to Figure 6, and. illustrating the instrument applied to a drawer on which two handles are to be installed; i t Figure 8 is a view of the instrument applied to a cupboard or cabinet door;

Figure 9 is a view of the instrument in flat comr pact-ed form for carrying in a tool box.

H) having a laterally projecting and rectilinear edge thereof at a right angle to the flange.

A marker mounting member in the former a fiatbar l3 of metal is slidable in the slot l2 and i can be rigidly secured in any selected position of Figure 6 is a view of the instrument applied to Referring specifically to the drawingythein vention in its present embcdiment' comprises-a flat and generally triangular shaped metal body gauging flangell along one edge thereof, and a slot 12 extending through the body from one" longitudinal adjustment to'the body by means of knurled headed set screw Hi threaded into the body to bear against the bar.

Adjacent one end; the bar i3 has fixed thereto a marker inthe formof alconi'cal and pointed pin l which is adapted? to col-act with an adjusts able marker also in the form of aconical and pointed pin it. The pin it is provided with a threaded shank ll extending through a longitudinalsl'ot is in the bar as and provided with a 101 knurled nut !9 by which the pin it; can be rigidly secured in any selected position of adjustment along the lengthflof theslot i8. Upontightening the nut 19, a shoulder (Figure'b) between the pin and shank I! is drawnagainst one side face 3 l of the bar l3,"and a "non-circular unthreaded portion 2! of the shank co -acts with the walls of the slot It to confine the marker against rota tion. By this adjustmentof the pin it, the

U spacing between the two pins 15 and IE can be varied to correspond with diiierent distances be tween the screw holes in different types and sizes of handles.

disposed for a prolongation of' the axis to be in intersecting relation to the axes of the pinsglfi and It so thatin effect these three axes are in a common plane. g1

An arm in the form of a rod .24 is right angularly bent at one end to provide a pivot pin 25 rotatable freely in the bore-23; and in order to releasably retain theipin 25 against axial displacement from the bore, the pin has an annular groove 25 (Figure l)';adjacent itsfree'end, into which a wirespring 21 is normally urged by being secured under stressto the body ill by a screw 28 passing through a suitable eye in an end of the spring and threaded into the body. 40

i The rod 24 constitutes a mounting for a gauging element co actablawith the gauging flange H and being in theformof a metal block 351 having a bore 3| therethrough slidably receiving the rod n 24 foradjustment thereof along the length of the rod. A knurled headed screw 32 is threaded through the block b 30 and is adapted to bear against therod to rigidly secure the block ina selected position of adjustment on'the rod. i

Asclearlyshown in Figure 3, the gauging face 3A of the blockilll relieved or inclined away from r the rod atopposite sides of the rod, as shown at.

.35,to'insure accurate fitting of the gauging face 34. on the t edge of al drawerwhen the block is same adjustment of the block as will be more fully described in the operation of the instrument,

1 which is as follows:

To use the instrument on a number of drawers of the same size which are each to have a single handle applied thereto, the marking pin 16 is first adjusted on the bar l3 to a center to center distance from the marking pin l5 corresponding to the spacing between the screw holes in the handle. The body I0 is now adjusted on the bar l3 for the two marking pins to be located for marking of the drawer front equidistantly at opposite sides of the vertical center of the drawer front when the inner face of the gauging flange I3 is held firmly against a side edge of the drawer front as indicated in Figure 6. The gauging block 30 is adjusted on the rod 24 for the gauging i face 34 of the block to engage the top edge of the drawer front when the marking pins are lo-..

cated for marking the drawer front, medially between its top and bottom edges, as shown in Figure 6, or at any other desired height :on the drawer front.

- With the instrument applied to the drawer front as shown in Figure 6, sufiicient pressure is exerted against the marking pins l5. and It for them to penetrate the drawer front and thus mark the location thereon to be drilled through for the handle securing screws. This operation is, of course, repeated on all drawer frontson which the handles are to be identically located,

from which it will be clear that accurately level and uniform locating of all handles can be easily and quickly obtained.

To use the instrument on a drawer to which two handles are to be applied as shown in Figure 1, suitable adjustment of the marking pin l6 is made to first obtain'the exact center to center distance between the pins l5 and I6 correspond ing to the spacing of the screw holes in the handles. -The body In is adjusted on the bar 1 I 3 to dispose the marking pins at the desired distance from one side edge of the drawer front,

. and the gauging block 30 is adjusted on the rod of the instrument, that the rod 24 be swung- 24 to dispose the marking pins at the desired height on the drawer front, all as shown in the fullline position of theinstrument in Figure 7.

The drawer front is now marked by the pins l5 and I6, and the instrument removed from the drawer front andv reapplied thereto at the opposite side thereof as shown in broken lines in Figure 7, it being necessary" in order for the gauging block 30 to function in this new position about its pivot pin 25 through one hundred eighty degrees to dispose the gauging block 30 for en- 7 When not in use, the'rod 24 can be removed from thebody l0 by'withdrawing the pivot pin 25 from the bore 23 after raising the spring 21 clear of the groove; The body I0 is moved along the bar l3 a sufficient distance to clear one end of the rod 24 when the pivot pin 25 at v the other end thereof is inserted into an opening 36 (shown in-Figure 1) through the bar l3 and the rod is disposed parallel to the bar, following which the body i0 is reversely shifted on the bar i3 until said one end of the rod 24 passes through the bore 23 of the ear 22. The set screw I i is now tightened to secure the body and rod against displacement. In this position of adjustment shown in Figure 9, the instrument forms a flat compact parcel for carrying in the tool box.
